lwi/lmwoeo I '3 mm/toe @260 z I i oAssIUs' CLAY LM-ER; OF NEW YORK, N.Y.

To all whom it nwiy concern? I 3 Be it liIlOWIL that I, OAssIUsCLAY-PALER,

a citizen" of the United States, and a resident of the city of New York,borou'ghof Manhattan, county and State of New York, have invented acertain new and useful Improvement in Refrigerating Apparatus, of which'the following is a specification.

. .This invention relates to refrigerating apparatus and-the meanswhereby said apparatus'is operated either when in a stationary positionor upon a refrigerating-car when thesame is movlng. i

It consists of certain novel parts and comb1- nations of partsarticularly pointed out in the claims conclu ing this specification.

I have shown in the accompanying drawings my invention in the form whichis at present preferred by me, although it will be understood thatvarious changes and modifications may be made therein withoutdeparting'from the spirit of my invention and without exceeding thescope of the concluding claims.

Figure 1 shows a cross-sectional elevation through the chamber in theend of a car containing my invention. Fig. 2 is a longitudinal elevationof the end of the car. Figs. -3,

' 4, and show details of a form of the pawlvand-ratchet device used inmy invention.

The chamber in the end of the car containing the refrigeratin apparatusmay be referred to as A, the c 'llroom or cold-storage chamberas B.

1 is a rotary compressor upon a shaft 2, mounted in bearings in a frame3, which is secured to the base 4 upon the fioor of the car. From thecompressor a pipe 5 leads into the pipes 6 6, &c., Within the condenser'Z. The pipe 8 leads from the said pipes 6 6, &c., into the refrigeratoror brine-cooler 9, and from this refrigerator or brine-cooler the pipe10 leads back to the compressor. Thus is formed a complete circuit fromthe com pressor through the condenser and refrigerator and return to thecompressor. I

11 is a pump suitably securedto the wall of the chamber A. From thispump leads a pipe 12, which enters into and coils around within therefrigerator 9. 'Emerging therefrom it passes through the partitionbetween the chambers A and B, extends through said chamber B, andreturns to the pump 11.

Through this pipe circulates the brine-or other suitable refrigeratingmaterial.

RQEFFRIGERATING APPARATUS-i Patented Dec. 25, 1906. I

In order, that the condenser-pipes 6 .6, &c.,

may be keptcool, I place above said pipes a tank 13, containing waterand having outlets 14 14, &c., through which the water may fall upon thepipes. To further aid in cooling 6 o said pipes, Iplace a fan 15 beneaththem,

which fan is caused to revolve by means of a belt 16, which extends toand is driven by the shaft 2. The brine-pum 11 is also driven from theshaft 2 throug shaft 18;

19 is a receptacle containing the lubricant for the rotary compressor,said lubricant being fed through the pipes 20 20*, and after circulatingthrough the compressor a portion of it is forced out into the pipe 5 andfinds its way IWill now proceed to describe theprincipal feature of myinvention,'which'lies in the novel means for automatically driving thecompressor, irrespective "of the direction in compressor may alwaysrotate in one direction without the necessity of employing an Thecompressor attendant to operate it. may be operated eitherfrom thecar-axle or from the oil-engine 21 within the car. The oil-engineoperates the compressor through the shaft 22, to which is aiiixed thesprocket Wheel 23, the shaft 2, to which is aflixedthe sprocket-Wheel24, and the chain belt 25, which engages with said sprocket-Wheels. Theoil-engine will of course 0 erate the compressor always in the onedesired direction that is, in the direction of'the"arrowsthe fluidentering-through the pipe 10 and dethe belt 17 and by means of the pipe20 back tothe receptacle 19. Y

which the can may be traveling, so that thepartingto the condenser bythe pipe 5. When it is desired to run from the car-axle,

the oil-engine may be stopped and the clutch mechanism 26 brought out ofengagement with the shaft 22, so that the sprocket-wheel 23 may runidle. The clutch vmechanism27 upon the shaft 28, which revolves inbearings'in the frame 3, may then be thrown into engagement, causingsaid shaft to revolve from the car-axle by means of the belt 29, whichis held in position and has its tension regulated by the idler-rollers30 and 30%, said rollers being drawn together by means of the spring 31,thus compensating for the motion of the springs upon which the carrests, the,

turning of curves, or any other variations be'-' tween the axle of thecar and theshaft 28; p f The shaft 28 has mounted on one end there:

wheel.

of the sprocket-wheel 32 which is free to revolve upon said shaft and isheld thereon by any suitable meansas, for example, the collar 33. Saidsprocket-wheel carries with it the pawls 34 34, which are suitablysecured thereto. Keyed to the shaft 28 is a ratchetwheel 35.

36 is a plate carrying projections 36" 36 This plate bears against theshoulder 28 of the shaft, and between said plate and ratchetwheel isinterposed any suitable frictional substance 37. Extending through thepawls is a pin 38, which on one side of the pawl rides upon the plate36, while on the other side it is borne upon by the spring 39, attachedto the sprocket-wheel.

40 is a spring bearing against the ratchet wheel and interposed betweenit and the frame 3.

41 is a stop or pin afhxed to the sprocket- A chain belt 42 extends fromthe sprocketwheel 32 to the sprocket-wheel 43 upon the shaft 2. Theother end of the shaft 28 has mounted thereon a gear-wheel 44, which isfree to revolve on said shaft. Aflixed to said gear-wheel are the pawls45 45.

46 is a ratchet-wheel keyed to the shaft 28, and 47 is a plate carryingprojections 47 47' and bearing against a shoulder 28 of the shaft.Between said plate and ratchetwheel is interposed a frictional substance48.

The pawls 45 have passing through them a pin 49, the projection of thispin on one side riding 011 the plate 47 and on'the other side beingborne upon by a spring 50. A spring 51 is interposed between the frame 3and theratchet-wheel and bears against said wheel.

52 is a pin or stop.

A gear-wheel 53 upon the shaft 2 meshes with the gear-wheel 44.

It is to be observed that the rotary compressor must always operate inthe direction of the arrow, so that the fluid to be compressed may enterby means of the pipe 10, be compressed, and travel to the condenser bypipe 5. lVe will assume now, taking Fig. 1 of the drawings, that the caris traveling toward us. The belt 29 will then revolve in the directionindicated by the arrow and of coursewil revolve the shaft 28 in thisdirection. This operation will cause the ratchetwheel 35 to revolve andfrictionally engage with the plate'36. Said plate will then be carriedaround until the projections 36 strike the stop 41. The pawls 34 34,which up to this point have been held out of operation by reason of thepin 38 therein riding on. the plate, will be pressed by means of thespring 39 intoengagement with the ratchetwheel, and by means of suchengagement the sprocket-wheel 32 will be driven and will drive the chainbelt 42 and sprocket-wheel 43, thus causing the shaft 2 to operate therotary compressor in the desired direction. In the meantime therevolution of the shaft 28 will cause frictional engagement, between theratchet-wheel 46 and plate 47, and said plate, having the pin 49 of thepawls riding thereon, will gradually raise said pawls out of engagementwith the ratchet-wheel, and the pro ecshaft and will cause thepawl-and-ratchet mechanism at the other end of the shaft to engage anddrive the gear-wheel 44, which in turn will drive the gear-wheel 53, andthus rotate the shaft 2 to drive the rotary compressor in the properdirection.

It will be seen that the pawl-and-ratchet mechanism I have abovedescribed for throwing either the gear-wheel 44 or the sprocketwheel 32.into and out of driving operation is similar, Figs. 1 and 3 illustratingthe mech anism driving the sprocket-wheel 32, while Fig. 5 shows it outof operation with relation to the gear-wheel 44.

above-described pawl-and-ratchet mechanism is shown simply as one meansof accomplishing the driving. Other means may be employed with the sameresults.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with a car, of refrigerating apparatus mountedthereon, a rotary compressor, driving connections between the compressorand the car-axle, means cooperating with the driving connections wherebythe compressor will be driven in one direction irrespective of thedirection of movement of the car, an engine, power connec tions betweenthe engine and the compressor, and means for shifting said powerconnection into and out of driving engagement with the engine.
